An error occurred while the system was attempting to create a log file. The error code (%4) specifies the cause: either the number of log files in the current directory exceeds 99, or the existing log files are too long. This issue prevents further logging until resolved.
Click steps to track your progress.
1. Access the specified log file directory (e.g., via network share or direct access to the NC file system) and delete old, unneeded log files to free up space.
2. Check the free storage space on the NC's target drive (e.g., D: drive, CF card) and archive or delete non-essential files to create more space.
3. If an existing log file is excessively large, rename or move it to force the system to create a new one.
4. Perform a file system check (e.g., using system utilities if available) on the storage device to detect and repair any corruption.
5. Verify that write protection is disabled on the storage device (e.g., physical switch on CF card) and that the system has write permissions to the log directory.
